Mainly, the current Mobile are connected by cellular network of base stations(cell sites). Which helps to interconnected to the public switched telephone network(PSTN).This all things are done by satellite phone.
The History of Mobile
Mobile is a latent word of Telephone. According to internal memories American Telephone and Telegraph try to discussed to developing a wireless phone in the history of Telephone in 1915. But their processing of developing of phone is dis act by the US. Their technology could undermine.
But the first time, NTT company of Japan had been lunched a commercial mobile phone service in 1978AD. From the date of November 2007. the number of mobile is reached near by 3.3 billion. Its number is half of the total human population. It makes the Mobile phone as a most widely spread technology and the most common stuff in the world.

Nokia mobile phone was the first mobile phone to enable internet connectivity and wireless email use. It was released in 1996 and make a new category of expensive phones called smart phones. The company of Japan NTT DoCoMo was launched a first mobile internet service under the i-Mode service. More then 798 million people around the world accessed the internet or equivalent mobile internet services like asWAP and i-Mode after 2007 AD. At least people are used more mobile rather then personal computer.

Process of power supplying in mobile phone.

Batteries are thr main sources of power supply of the mobile phone. Batteries are recharged by the USB. USB is the power supply of the mobile phone from electricity supply. Power Supply are transfers from mains power, cigarette lighter socket in a car using an adapter. The main form of mobile phone batteries were nickel metal-hydride. So that the weight of batteries was less and small size. Batteries which was made by Lithium-ion have less voltage and lighter then those batteries made by nickel metal-hydride. Lithium-polymer batteries are used in the mobile phone now a days, it was made by the Lithium-ion. The main advantages of this batteries is lower weight and the possibility to make shape other than strict cuboid. Mobile phones are used alternate power sources,including solar cells.

Microchip is the main require of cellphones in the addition of the battery, that is called Subscriber Identity module or SIM card to process the mobile phone. SIM card is installed underneath the battery in the rear of the unit. When SIM card is properly activated the phones configuration stores. The information about the phone itself. SIM card are used in the another phone when subscriber are removes.
Unique numerical identifier is used in SIM card activate. The identifier is locked down and the card is permanently locked in to the activating network when it is once activated. Due to thus reason most of the retailers will refuse the return of an activated SIM Card. All the data programmed are store into the memory if there is shortage of SIM Card. The MSL is also Service provider to gets payment for the phone that was purchased or 'leased'.
Mobile is one of the Media of communication.

Mobile is considered as a media of communication. It became a mass media channel in 1998 when Radiolinja of Finland published a first ringing tones were sold in the market. After that many media like news, video games, jokes, horoscopes,TV content and advertising. More then 31 Billion People are used mobile where as Internet is connected in the year of 2006. The latest market mobile have many types of function with there cost. The mobile content music on phone was worth is 9.3 Billion dollar. Similarly, those mobile which have games in the latest market mobile cost is 5 billion dollar.

The cuurent technologies of computers in the world markets

According to change in time and technology there is a large variation among the past,present and future as well. We should know what is inside the computer? When the service technician was installing somethings for you may be peeked. A computer is a large threatening machine when you look inside the CPU of computer at first time in your life. But when you see a parts of the computer once you know about the different parts of that make up complete computer it gets a lot easier to know. At present day computer have at least eight components but the advance computer have more then eight components. What are the main components and how they are use for? We are started with beginning to know you.
The Power Supply: The power supply is the process of supplying electricity to all of the components in your computer. It is positioned in one of the corners of the computer in a rectangular box. To find the power of the computer you should look where the power cable plugs the computer and then you find the power supply. Power supplies are calculated in Wattage and come 50 watt increments(500 watt,550,600, etc)
Motherboard: motherboard is the main components of the computer system. All the components are connected into the main components called motherboard. It is not said to be a brain of the computer system. But it holds the brain and helps it act together with all the other components of the machine.
Important components of the computer CPU: Central Processing Unit is know as the important components of the computer system. Because it is know as the brain of the computer system and nothing is going to happen without it. All the computer calculation, processing as well as performed by a computer are carried out inside its CPU. It is responsible for activating and controlling the operation of other units or the system. It is measured in gigahertz(Ghz) and ti is faster then 3.8Ghz at present.
Random Access Memory: Random Access Memory is used as temporary working storage for the computer.RAM have different types with their speed, but it should match with your motherboard. It can work properly. If you have more RAM in your computer it works as better as those computer who have less RAM in computer hardware.
Hard Drive: It is a storage device for every things.In the hard drive operating system(Windows XP, etc) are includes,games,and different types of software etc are also available. The capacity of the hard drive is being continuously increasing according to change in time and technology. In the interval of few years its capacity have gone from around 20 MB to over 500 GB and more. Because of storing device hard drive can store a lot of information, games, pictures, videos, application,and more.
Cooling fans: It is the main part of the computer system. Cooling fans is connected with the CPU to cool down the heating of components of the computer. It helps to cool down the heat generated by other components, such as power supply, the CPU, and some high-end videos cards. Cooling fans puts computer overheats and breaks, while most of the noise you hear coming from a computer can be credited to the cooling fans,it is the parts of computer.
The seventh and final components is the combination of different devices. They are; Cd-rom,DVD drives, Floppy disk and backup devices such as external hard drive.

What do you mean by operating systems of computers technology?

What is an operating system?

An operating system is a set of programs that manages the hardware and resources for the computer system. It also handles files, programs and deals with other requests. It controls over the Input and output devices. It plays the role of an interface between the users and the computer for interaction between them. The computer is use less without operating system. The example of operating system are: Ms-DOS, Windows 95/98/xp, UNIX, LINUX etc. A set of programs that controls the entire operation of the computer such as handling Input/Output operation, user request, interrupts etc is known as operating system. Operating system manages the resources of a computer system and schedules its operation. It is a master supervisory program which provides a friendly interface for the user to interact with the computer and its peripherals and different application software as well as an environment for program to execute.
Operating System(OS) is a computer program (system Software) that act as an intermediate between the user and computer hardware. This is the first software we see when we turn on the computer and again the last software we see when the computer is turned off. As computer consists of various resources (or parts) like Memory,CPU, Disks etc. it's very difficult for the user of computer to understand how to operate them directly. So, OS becomes the interpreter between the computer hardware and user. It interprets the command of users to the hardware and presents the output to user in a suitable format produced bu hardware. For example, if we want to save our Bio-Data into the floppy disk, then we don't know "how to write" or "where to write" inside the floppy disk, but our duty is simple to give command to the operating system (i.e. Save into floppy) and now it's the job of operating system to tell the floppy drive what to do exactly. In short,OS acts as an interface and hides the every details of working principal of computer from the user, thus operating system can be regarded as resources manager.
Also operating System provides user a high level abstraction. Without knowing much more internal details of any devices the user can operate them through Operating system.

What are the Functions of an Operating System?
The main functions of an operating system are as follows:

• Memory Management: The basic function of an operating system is to manages the memory available to application programs in the computer. The operating system determine the amount of memory required for the programs instructions and for data. It allocates the amount of memory required and loads the program into RAM(Read Access memory).
• File Input/Output Management: One of the most important functions of an operating system is to manage the file input and the output. It manages the files stored on hard disk and other storage devices. It also provides the facilities such as to create the files, opening the files for read and writing trans fore the data and so on.
• Device Input/Output Management: The another important function on an operating system is to manage the input and output devices.It plays a role of an interpreter for various devices and language. It uses the specials program known as device drivers to translate the input/output request into commands to specified the hardware devices.
• CPU management: The operating system handles the processing jobs of the CPU. It helps the CPU to schedule its activities to meet the demand of the users and various parts of the CPU and the computer itself. The CPU gets the jobs from the keyboard or a storage medium , puts it into the memory , process the input and passes the results to the output devices.
• Operating in Batch Mode: Most of the operating system allows for operating in batch mode. In batch mode operating system user can instruct the operating system to execute a number of program one after another.
  

What are the main basic types of Operating System?
Operating System can be classified into following categories:

• Single-user operating system: In the operating system the single-user operating system can work at a time. I mean this operating system provides an environment where single-user can work at a time. It provides all the necessary resources to the user. The example of single-user operating system are Ms-Dos,Windows 95,98,XP,etc.
• Multi-user operating System: This is operating system allows more than one user to share and access the data and programs at a time. This operating system provides the total time into a number of time slices and schedule the task one after another in a given priority. The example of multi-user operating system are, UNIX,LINUX,Windows NT.
• Multi-tasking operating system: This operating system allows a PC(personal computer) to perform more than one task at a time.There are different types of multi-tasking operating system. Such as context switching, co-operative multi-tasking, Time-slice multi-tasking.
• Multi-processing operating system: In the operating system more than one processor are linked together in co-ordinate way. This processor share main memory and input/output devices.These processors can execute(run) different independent programs simultaneously. They can also execute the part of the same program. The example of multi-processing operating system are UNIX,LINUX,MVS etc.
• Real-time Operating System: This operating system is as online operating system that responds to input immediately. This operating system is designed for controlling and monitoring the external activities with time constrains. It is useful for controlling the external activities such as load shedding, traffic lights etc. The example of real time operating system are ccp, Bso,/RTOS.

• Simulator: Simulator is the system software that is used to simulate the execution of the programs of the other computer. This types of software is used to learn the subjects of technology nature.
• Emulator: Emulator is a software that is used to mimics the function of other programs,computer,modem,printer etc. It is also used for converting the program written in one language into other language.
• Utility Software: It is a software that is related with the utilities of the computer system. Generally it is used in file management, memory management, disks repairing, virus scanning etc. The example of utility software are: Norton Utilities, PC Tools, Scan disk, defragmenter etc.
  

Application Software: It is a software that is used for specific purposes. It is needed for the user to run the program in the computer. Generally, this software are developed by using the high level language. The example of application software are: Word processing, Spread sheet, Data based management System(DBMS),Graphics etc.
Application software are mainly classified into two classes they are:

1. Packaged Software
2. Tailored Software

Packaged Software: It is readymade and advance and standered software use for sprcific purposes. It is developed in the big warehouse by the group of export software developers or programmes. For example the Microsoft co-operation,USA developeds the different types of packaged software. Such as microsoft offices packages, microsoft visual basis etc. This software are equppied with all the essential tools and technology to enhance(to expand) user poductivity. Examples of packaged software are word processing, Data base Management System(DBMS), Graphics, Animation softwares etc.

Tailored Software: Tailored software is the special types of software that is design or developed as a requirements of individuals to organization.It is a smalls moftware that is developed in high level language for specific small purpose, For example: Accounting Software, Payrool Software, Departments store Software, Software for Bank etc are the tailored software.
